  • Publication number: 20150033944
    Abstract: A method for waste gas purification in dust separation plants making use of a device (16) for generating a negative pressure, in particular by means of steam jet ejector pumps or mechanical vacuum pumps, wherein the waste gas coming from a vacuum chamber (15) is conducted into a cyclone separator (12), and that the method steps of coarse separation of particles from the waste gas and fine dust separation of particles from the waste gas and gas cooling in the cyclone separator (12) are carried out in succession in such a way that the waste gas, after coarse purification has taken place, is conducted directly via a fine dust filter (13) installed in the cyclone separator (12) and subsequently through a gas cooler (14), which follows the fine dust filter (13), into a suction line (2) connected to the device (16) for generating a negative pressure and to the device (16).

  • Patent number: 8603387
    Abstract: A water-cooled cover for a treatment vessel for metal melts, wherein the preferably refractorily lined treatment vessel serves in particular for the treatment of liquid metal, in particular of steel, by blowing in solids or gases, or inductive stirring at atmosphere or in vacuum. The cover is formed dome-like, wherein the ratio of inner clear height (h) to inner clear diameter (D) of a flange of the cover is at least 0.2. On the side facing the metal melt, an inner wall of the cover is formed substantially smooth and free of grooves and gaps. Cooling channels arranged on the outer side of the inner wall so that the surface temperature of the inner wall is maintained at a temperature of maximum 350° C.
